To analyze the power spectral density and PAPR of FDMA and SC-FDM

Literature emphasizes the orthogonal frequency division multiplexing for high data rate transmission over wireless channels. This is most popular multi carrier communication technique. Due to its robustness against frequency selective fading channels, it copes with the problem of limiting bandwidth and power for transmitting higher data over wireless mobile systems [1]. However, it suffers from a high peak to average power ratio which may be trouble in uplink transmission as costly high power linear amplifiers are needed in user terminals. So, for uplink transmission, one system required that have low peak to average power ratio. In this paper, a methodology of implementing the technique is proposed which has low peak to average power ratio.

To analyze the peak to average power ratio for both techniques
